Tom Wolf maintains double-digit lead over Tom Corbett, poll shows

Tom Wolf of York County holds a 22 percentage point lead over incumbent Tom Corbett in the race for governor, according to poll results released Wednesday by Franklin & Marshall.

Wolf leads 47 percent to 25 percent, with 27 percent responding they "don't know" who to vote for, according to the poll results.

Only 27 percent of voters -- or about one in four -- say Corbett is doing an "excellent" or "good" job, the poll showed. About 59 percent of voters believe the state is "off on the wrong track."

The findings were based on interviews conducted June 23-29 at the Center for Opinion Research at Franklin & Marshall College. There were 502 registered voters, including 249 Democrats, 185 Republicans and 67 Independents or third-party voters. The margin of error is +/- 4.4 percentage points.
